GluR4 expression on pre-OLs. Untreated controls (A-C) or cultures chronically incubated with TNF-α (D-F) or LPS (G-I) were assessed immunocytochemically for GluR4 subunit expression (red) co-localised with pre-OLs (green). The nucleus was stained with Hoechst fluorescent dye (20 × magnification), scale bar = 10 μm.
